We normally flew in groups of eight, less often twelve. Red flight led the mission and white flight accompanied. For very large missions (I remember one of thirty six ships) we used blue, green and yellow as flight designations.
The only true mistake in the writeup is the statement "divided into
groups of three or four". We never flew in a group of three unless someone had to return early. This
statement misses the binary principle in fighter tactics. One of the great strengths of American
fighter tactics was the unit of 2, leader and wingman. They could protect each other. If you were
alone, you were ALONE!
Even the group of four was a pair of twos, the flight leader and wingman and the element leader and his wingman!
